Mine is most definately NOT the Nightmare pack. OF course you must "gamble" with your crowns to get certain items from theses packs, but I have now spent over $50 (bought at the discounted 60,000 for $60 rate) and still have not received the Nightmare mount.
I have never had to spend this much money to still not receive the mount. Very frustrating. BUT, to answer the initial question now that I have vented my frustrations, I prefer the Dragon Hoard pack. The gear is great and the Bone Dragon mount is my favorite mount in the game.
I'm with CFDaddy...I finally got my Nightmare after spending upwards of 86,000 Crowns! But at least the items were compatible with my home, so it wasn't a total loss. I guess I could say it's my favorite pack, but really, that's only because the items it provides are good for the wizard I am using now (a Necromancer)
Well, the black hood with the red eyes, is one of the coolest looking hats in the game and even the wand is wicked looking... Wish they would have sold them at the crown shop, I am sure they would have made a fortune, especially if you could dye it with the colors you wanted... White with black eyes, or light blue with purple eyes... etc...
That is about the only thing I liked about the nightmare packs...
Now, the DragonHoard pack, I loved the dragonwings mount, the sword looks too awesome...
Did not like anything about the wyvern packs, did not buy a single pack!
The most intense crown buying and pack opening experience came of course from the Nightmare pack. Not even the Wyvern's Hoard pack came close to that kind of action.
Not to mention, the coolest armor in the game that I have seen so far, the Grimwraith Umbral armor, comes from that pack!
The nightmare pack is so popular because it's only around for a temporary amount of time.
not true its got tons of sweet pets and i even got permanent bat wings and a nightmare with only a few packs that is why its popular and its most likely coming next year as well so its not like gone for good after this month
